Why it’s time to re-think your approach to Maintenance?

Unplanned maintenance and the resulting production downtime are the bane of most organizations. Deloitte reports that such downtime costs industrial manufacturers £37 billion [$50 billion], and that 42% downtime is caused by equipment failure.
The combination of connected technology (the Industrial Internet of Things) becoming available at lower costs and greater data analytics makes it possible to monitor almost any machine and predict failure before it happens. This makes it possible for organizations to identify problems and plan downtime to suit their own schedule.
However, access to a range of sensors is only part of the overall picture. “Intelligent maintenance is more than just technology and products, it’s actually a way of thinking,” says Richard Jeffers, Technical Director Northern Europe at RS. “It’s about anticipating potential failure and taking the right action to prevent or reduce the impact of that failure on your operations. Technology is what you use to enable and make predicting failure easier.”
The first step for organizations looking to reduce their unplanned maintenance, according to Jeffers, is to recognize the value of a predictive approach. Deloitte has found that predictive maintenance can “reduce the time required to plan maintenance by 20% to 50%, increase equipment uptime and availability by 10% to 20%, and reduce overall maintenance costs by 5% to 10%”. For many organizations, and their maintenance teams, the big question around smarter maintenance is where to start. For a lot of businesses, the test and learn approach works best as individuals and the organization as a whole establish the best solutions for their needs.
“I visited a customer’s logistics site recently and they have taken a very sensible approach to introducing maintenance intelligence into the business,” recalls Jeffers. “They had around 800 motors in their building but had identified 13 that were crucial to their operations, so they have put temperature and vibration sensors on those motors to alert the maintenance team if they start to fail. This is a trial, but the business will start to roll out the technology to other motors over the next year as the technology proves itself.”
For many organizations, there is a need for expert help and access to knowledge that will help them adopt new technology. Recent research by RS and the Chartered Institute of Procurement and Supply showed that 54% of procurement and supply professionals in the maintenance, repair and operations function want access to knowledge services from suppliers, not just the products.
“RS provides a range of sensors for customers looking to adopt and enable their smart maintenance strategy,” says Jeffers. “But we also have expertise within the business to help customers understand and make the most of IIoT. We are using this technology in our own warehouse in Nuneaton, so we have first-hand knowledge of the technology in practice.”
